Abstract
The invention relates to an exhaust turbocharger which has a wastegate valve (2) and a thrust circulation valve (5), which can be actuated by a single, common actuator (8), wherein the actuation of the thrust circulation valve is dependent on the positioning velocity of the actuator.
Description
The present invention relates to a kind of exhaust gas turbocharger, it has a waste gate valve and a towing astern bypass valve (Schubumlaufventil).
The internal-combustion engine being carried out supercharging by a kind of exhaust gas turbocharger is outstanding by the following layout that guides for fresh air and waste gas:
In common blower operations, described waste gas flow into turbo machine from internal-combustion engine, and drives the turbine rotor of this turbo machine to rotate.Because described turbine rotor is connected with the compressor drum of described exhaust gas turbocharger by a common axle, described compressor drum equally also rotates, and compresses for air before entering into internal-combustion engine in suction side.By this way, more fuel can be mixed in each cylinder stroke.Which thereby enhance the torque of described internal-combustion engine.Figure 1 illustrates this working state.Which show turbine 1, waste gate valve 2, axle 3, compressor 4, towing astern bypass valve 5, air throttle 6 and internal-combustion engine 7.It can be seen, waste gate valve 2 is closed, and towing astern bypass valve 5 cuts out, and air throttle 6 is opened completely.Control for supercharging can realize as follows, namely makes a part of exhaust mass stream flow through described turbine rotor from the side by described waste gate valve.
It is pointed out that for representing that clearly object does not show some parts of airflow guide in FIG.Catalytic cleaner after being disposed in turbine comprising the fuel tank/crankcase bleeder and after Air flow meter, charger-air cooler, be arranged after the compressor before the air-strainer, before such as is disposed in compressor is disposed in compressor is disposed in air throttle.Equally, the EGR that may exist or secondary air inlet is also eliminated.
When driver no longer refuels, then internal-combustion engine from blower operations be transitioned into throttled operation in other words towing astern operate inertia traveling (Schubbetrieb) in other words.At this moment open described waste gate valve 2 and close described air throttle 6.First the rotor of described exhaust gas turbocharger rotates due to its inertia, then because the final very fast opening feature of described waste gate valve still continues to rotate with very high speed, thus makes described compressor continue conveying fresh air.When compressor continues conveying, but the fresh air that internal-combustion engine accepts is than time few under working state before, then the pressure after making compressor along with the reduction of air mass flow will increase.
Fig. 3 shows the characteristic curve of the compressor of exhaust gas turbocharger.Here, abscissa represents flow mass M S, represents pressure coefficient PQ along y coordinate.PG represents surge boundary, and SG represents and fills up the limit (Stopfgrenze).TDL relates to Iso rotating speed line.
As can be seen from Figure 3, the stable operation of compressor in the scope of low discharge is subject to the restriction of described surge boundary PG.When exceeding described surge boundary, compressor no longer has the ability of carrying out with overcoming high pressure level carrying.May occur: the air gathered refluxes through described compressor, i.e. so-called surge (Pumpen).This compressor surge should be avoided, because the pressure surge occurred may cause strong mechanical load.In addition, described surge can be perceived as uncomfortable noise.
In order to avoid the surge of compressor in said case, can be discharged by the fresh air compressed by towing astern bypass valve after the compressor.In order to not make the measurement distortion of described Air flow meter, advantageously, the air of discharge was again imported in described suction side before described compressor, thus make described compressor carry air in the loop.If only continue the very short time to the transition of the engine operation of solar term, such as within the scope of to two second, as situation about coexisting when shifting gears, then, when next again proposing very large torque-demand to motor, again close described towing astern bypass valve and waste gate valve.The rotor of described exhaust gas turbocharger keeps its rotating speed approx within the endurance that this is very short, and again reaches required boost pressure level very fast after clutch engages.
Figure 2 illustrates the operating mode of towing astern in other words of described solar term.Can find out therefrom, described waste gate valve is opened, the described towing astern bypass valve 5 of same unlatching, and closes described air throttle 6.
Known, by means of one self, the actuator that is attached to described waste gate valve to be to operate described waste gate valve.In addition known, also by means of one self, the actuator that is attached to described waste gate valve to be to operate described towing astern bypass valve.Described wastegate innervalve assembly and described towing astern bypass innervalve assembly separately individually by means of self supply line (they can electricity ground or pneumatically carry out work) manipulate.This is except very high cost, in described exhaust gas turbocharger is carried out encapsulating, too there is shortcoming, because described actuator must be arranged on turbocharger, and therefore increase the installing space of described exhaust gas turbocharger required in engine compartment.
